DESCRIPTION  
The device is a step-down controller specifically de-  
signed to provide extremely high efficiency conver-  
sion, with losses current sensing tecnique.  
The "constant on-time" topology assures fast load  
transient response. The embedded "voltage feed-for-  
ward" provides nearly constant switching frequency  
operation.  
An integrator can be introduced in the control loop to  
reduce the static output voltage error.  
APPLICATIONS  
I/O BUS FOR CPU CORE SUPPLY  
NOTEBOOK COMPUTERS  
NETWORKING DC-DC  
DISTRIBUTED POWER  
The available remote sensing improve the static and  
dynamic regulation recovering the wires voltage  
drop. Pulse skipping technique reduces power con-  
sumption at light load. Drivers current capability al-  
lows output current in excess of 20A.
